Camera EXIF (ISO, shutter, lens, GPS) is preserved by default during TIFF → JPEG conversion when both formats support metadata (JPG, TIFF, WebP, PSD). Use the privacy option to strip metadata before download if you want to share images without geolocation.
我能一次把成百上千的 TIFF 文件转换到 JPEG 吗?

Yes — drag multiple TIFF files into the upload zone and we queue them in parallel. Free users get 100MB per file; Premium has no per-file cap and runs more parallel workers, so a 200-image batch typically finishes in under two minutes.
Default behaviour is 1:1 — your JPEG output has the same pixel dimensions as the source TIFF. ICO output is the exception (it produces a multi-resolution stack: 16/32/48/64/128/256). If you need to resize as part of the conversion, use /resize/ after conversion.
Yes — uploaded TIFF files are processed in isolated workers and deleted within minutes. We never read, store, or share the pixel data. The full privacy policy and retention window are documented at /privacy/.
